I'm just a programmer without GIS-skills as such. Hence this question:
- I have a lot of polygons; actually each private-owned real estate in my country.
- I also have "counties" as polygons.
- In each county there are a varying number of (administrative) subdivisions (2 to 55) - and each real estate belongs in one of these subdivisions.
- But real estates are divided by roads and there are blank areas without any relation to the subdivisions.
My goal is
- To have just one polygon for each subdivision.
- Have the blank spaces between real-estate-polygons divided evenly between subdivisions.
- The county marks the outer border.
All the red boxes are merged. All the green are merged. The spaces between are shared. The black box is the outer limit.
Is there a readily available tool that can do this easily? Like QGis, ArcGIS, a db-engine or library/API? I've tried perusing the different options, I've tried testing various approaches, but to no avail.
If there aren't any tools, I guess I need to program it myself. Any thoughts?
If there is a term describing the process above, please let me know: I'm such a GIS-noob, so I don't even know what to Google :-)
